public class CAST5Cipher
extends BlockCipherWithPadding

CAST-128 (alternatively CAST5) is a block cipher created in 1996 by Carlisle Adams and Stafford Tavares. It is a 12- or 16-round Feistel network with a 64-bit block size and a key size of between 40 to 128 bits (but only in 8-bit increments). The full 16 rounds are used when the key size is longer than 80 bits. All the algorithms herein are from the Internet RFC's RFC2144 - CAST5 (64bit block, 40-128bit key).
